    t seem as answer to me Reply with quote animartco animartco Posts 117 Joined Sat Jan 21 2012 12 56 pm Sat Jun 08 2013 12 45 pm Again this seems a badly worded question with movement added as an afterthought There is quite a lot of energy expended in moving breathing growing etc which being energy cannot return to the food chain It is therefore rightly counted a loss Which means that for the system to continue that energy must be replaced I am sure you can guess how this is done Reply with quote jeffz jeffz Posts 5 Joined Fri Jul 12 2013 5 44 am Thu Jul 18 2013 2 30 am Honestly I do not understand what actually your question is I do not think that energy get end as it is constantly being used in producing food and to make a working food chain It is better to say that energy get replaced but not lost Hope you understand Reply with quote animartco animartco Posts 117 Joined Sat Jan 21 2012 12 56 pm Sat Sep 07 2013 3 47 pm Putting it simply every movement we make expends energy which Leaves our system i e is lost We replace it by eating The same thing is happening in an entire ecosystem WE know how the ecosystem replaces that energy but there is the question of what happens to the expended energy that is lost It is in the form of electricity so perhaps it doesn t actually leave the Earth but is collected in the magnetosphere yes where does it go Anybody Reply with quote pathfinder pathfinder Posts 2 Joined Wed Sep 11 2013 1 27 am Re Energy respiration and photosynthesis Wed Sep 11 2013 2 07 am well to begin with the

    testing certain species of exotic parasitoid wasp which control the BMSBs in their native Asian environments These little wasps would be heartily welcomed by those of us with a BMSB problem and we also enjoy seeing the occasional pheasant So what do you folks think about the issue Reply with quote JorgeLobo JorgeLobo Posts 424 Joined Mon Nov 17 2008 12 12 am Re The Himalayan Snowcock in Nevada Sun Jun 10 2012 5 20 pm Good point and not all current residents of an ecosystem can be interpreted to have been here forever I ll add that zebra mussel is not necssarily a problem In the Great Lakes it s been credited with reduction of particulate pollution and subsequent increase in fish populations On the otherside they ve reduced populations of native mussels and been the source of avian botulism That it blocks cooling vents for power plants is not an environmental problem per se You can even see fishing shows targeting the hated snakeheads Reply with quote thoffnagle thoffnagle Posts 31 Joined Tue Nov 27 2012 4 10 pm Tue Jun 11 2013 4 07 pm Exotic species should never be introduced Period The examples that each of you gave as being benign are not benign Brown trout outcompete native trouts and eat native species They are a huge problem in places like the Grand Canyon where they devour the endangered native fishes Pheasants outcompete native grouse such as sage grouse and prairie chickens which are now threatened species I see no reason why hunters couldn t hunt them instead of pheasants Chukars and Hungarian partridge compete with California and Gambel s quail While zebra and quagga mussels do clean up water I questions JorgeLobo s contention that they ve been credited with subsequent increase in fish populations

    Every year the influenza kills a lot of people The dangerous time is the late winter as far as I know I am in Germany by the way There are viral shockwaves every year but how does for example this virus do this Is there some scheme I would expect from them to be tricky Be there where the beings are weaker than usual Winter So does the virus spread out always from the cold to the warmer parts From a physical perspection Are they part of the air or do they necessarily sink down If so if they sink down if I touch something infected in June did they survive Is it just my body beeing more resistent in summer times Thanks for your comments and best wishes Jens Reply with quote claudepa claudepa Posts 27 Joined Tue Nov 03 2015 12 43 pm Re How does a Virus survive Sun Feb 14 2016 10 04 am Hi I cannot answer all your questions But to the question of is a virus a living entity my feeling is It is a question a the definition of what is life For some life is where are nucleic acids which contain the genetic information According to this definition a virus can be considered as a living entity For other life is self reproduction of the organism Then a virus is not a living organism since it needs to infect a cell to reproduce Reply with quote jonmoulton jonmoulton Posts 442 Joined Fri Feb 15 2008 5 38 pm Location Philomath Oregon USA Website Re How does a Virus survive Tue Feb 16 2016 5 06 pm The reservoir of infective viruses is usually within hosts though the virus can remain infective in the environment for a while Influenza can replicate in
